What happened on 4 November

5 markets spent time below zero on 4 November: South Australia for 10 h 40 minD, Queensland for 7 h 40 minD, Victoria for 7 h 15 minD, New South Wales for 35 minD and Tasmania for 15 minD. The longest unbroken run was in South Australia, 4 h 40 minD from 14:30–19:10 ACDT; the lowest price there during the day was −A$259D/MWh. The run spanned both daytime and evening hours local time. This site does not publish a generation mix for the NEM regions, so the solar and wind share in those intervals is not shown. Denmark DK2 spiked to DKK 2,763/MWhD (about 417D USD/MWh) in the hour from 18:00 CET, above our fixed threshold of 300 USD/MWh.

Great Britain had the cleanest mix of the grids we meter, 38.0D % renewable over the day, with wind at 26.7D %. Denmark followed at 33.0D % renewable with wind 10.1D % and solar 22.8D %. Taiwan followed at 9.8D % renewable with wind 1.2D % and solar 7.3D %. Across the 8D markets with a full day of metered demand, 2,139,152D MWh was used, Great Britain the largest at 37.0D % of it.

The biggest day-on-day moves in electricity used were Victoria at +11.4D % and New South Wales at −7.7D %. Denmark's renewable share fell by 15.2D points, from 48.2D %.

How to read this. The 4 November recap covers 15D markets (8D with a full day of demand) and was frozen at 00:30 UTC on 5 November; later operator revisions are not applied. A D badge marks a number we calculated from the operators' metered data, an M badge one published as is. Durations add up priced intervals below zero, clock times are each market's local time, and shares are energy-weighted over the day. Definitions and limits are in the methodology.
